There is no proof Obama was at the hospital, nor filled out the birth certificate. They did not live together after the alleged birth.
Obama Sr. never lived at the address published by the Honolulu newspaper in the birth announcement. This is in the INS files.
Obama’s age listed on the alleged BC is 25. This is not correct. His INS records indicate he wrote his birth 18 June 1934. This makes him 27 in 1961.
The argument here is that the term could not have been used at all, because it's a nationality. Obama may or may not have been at the hospital, but the fact remains that nationalities can be used and indeed have been.
